ANDREW WICKEY, OF EAST CHICAGO, INDIANA.

BALING-PRESS.

Application filed June 7, 1915.

To all whom it may concern Be it known thatv I, ANDREW W1oKEY,-a citizen of the United States, and a resident of East Chicago, county of Lake, and State of Indiana, have invented certain new and useful Improvements in Baling-Presses, ,of which the following is declared to be a full, clear, and exact description.

This invention relates to baling presses, and it has been designed particularly for baling scrap paper, although it is not necessarily limited to such use, as it may well be used for baling other commodities.

One object of this invention is to provide novel gearing for operating the plunger of the baling press, whereby great power 1s obtained; another object is to provide a power operated paper. baling press with means for-automatically stopping the plunger at the upper ends of its strokes.

Other objects and advantages, will be made apparent in the course. of this sp ecification, and with all of said objects in vlew, this invention consists in the several novel features of construction, arrangement and combination of parts hereinafter fully set forth and claimed.

The invention is clearly illustrated in the accompanying drawings, in which:

Figure 1 is a front elevation of the upper portion of a paper baling press with my improved gearing applied thereto; Fig. 2 is a plan thereof; Fig; 3 is a vertical, cross section taken on line 33 of Fig. 1, showing the plunger at the upper limit of its stroke; Fig. 4 is a section taken on the line of Fig. 1, showing the plunger partly depressed Fig. 5 is a detail, vertical, cross section taken on line 5*5 of Fig. 1; and Fig. 6 is a view partly in rear elevation and partly in vertical, longitudinal section taken on the hue 66 of Fig. 2, and showing a certain trip mechanism for throwing a certain clutch out of action.

Referring to said drawings, 10, designates a rectangular box-like, compression chamher which receives the commodity to be baled. Said box or compression chamberis open at the top and front and the front is closed by a door or cover, 10. The box is preferably constructed of sheet metal plates reinforced by angle-iron bars, 11.

The plunger, 12, has a plunger head 13, carried by two arms, 14, bolted or otherwise secured to it, and each formed with a continuous rack, 15, comprising twoparallel,

oppositely disposed portions, 16, 16, (see Fig. 5), joined at their ends by curved portlons, 17. Meshing with each rack is a pinion, 18, fastupon shafts, 19, 19, journaled in bearing brackets, 20, 21, carried by the box, 10. The inner ends, 22, of the shafts, 19,

project into continuous grooves, 23, one

formed in each arm, 14, adjacent to and running parallel with the rack,15, and the pinions are thereby held in mesh with the racks, which, in the operation of the machine, are driven by said pinions to travel up and down with a forward and backward oscillatory movement at the ends of the strokes.

Upon the shafts, 19, are secured gear wheels, 24, which mesh with pinions, 25, fast on a drive shaft, 26, journaled in bearings, 27, mounted on the box, 10, said shaft, 26, extending from one side of the press to the other, as seen in Figs. 1 and 2. The gear wheels, 24, and pinions, 25, are surrounded by guards, 28, secured to the bearing brackets, 27. Said drive shaft, 26, is driven from any suitable source of motive power, and it is here shown as having a drive wheel or pulley, 29, loosely, mounted thereon and arranged to be coupled to the shaft, 26, by a clutch, 30, connected by links, 33, to a hand lever, 31, fulcrumed on posts, 32. A post, 34, secured to the box, 10, projects upward therefrom and is straddled by two lugs, 34*, of the slidable part, 35, of the clutch and keeps said slidable part from turning. The hand lever, 31, has a channel-shaped part, 36, extending across the shaft, 26, and one of the links, 33, is secured to said part, 36. Braces, 37 38, secured to the box and bearing bracket, 27, act to brace the posts, 32. A coiled compression spring, 39, confined between the front angle-iron bar, 11, and a shoulder or a rod, 40, secured to the hand lever, 31, and extending down through a hole in the front angle-iron bar, 11, operates to hold the hand lever in either of its positions. In Figs. 1 and 2, the hand lever is shown in position occupied when the clutch is thrown out.

The means for automatically unclutching the clutch at the top of the plunger strokes may conveniently comprise a link, 41, guided to move vertically by anangle-iron bar, 42, secured to the frame of the press; said link, 41, is connected to the channel-shaped part, 36, of the hand lever. The lower end of said link, 41, is arranged to be struck by the plunger head at or near the endof its upper strokes, and raised, thereby starting the hand lever back until the pivot points ions, and the racks are forced down, carrying with them the arms and head of the plunger, thereby compressing the contents of the compression chamber. As the curved parts of the racks pass under the pinions great power is developed and the contents are: thereby subjected to great pressure. It is to be noticed that the plunger head does not extend at right angles to the arms,but

is inclined downward toward the side of the box containing-the door (see Fig. 4) whereby when the plunger reaches the lower end of its stroke and the rackspass under the pinions, the arms have tilted over, bringing the plunger head into a horizontal position. When theplungerreaches the top of its stroke the automatic stop mechanism throws out the clutch and stops the rotation of the drive shaft and gears; Another supply of waste paper or other material is placed upon'that already compressed and the whole is compressed as before, until a full bale is obtained. On the last compression stroke of the plunger, which completes the bale, the clutch is thrown out by hand, when the upper curved ends of the racks are on the dead center withrespect to the pinions. By reason thereof the plunger head is held horizontal so as to make a square-ended bale, and furthermore, the plunger is thereby held in position against the expansive forces of the compressed bale, which may be tied up in the usual manner.

I am aware that more or less variation of the exact details of construction is possible without departing from' the spirit of this invention, and I desire, therefore, not

- to limit myself t0 the exact forms of con struction shown and described, but intend in the following claims to point out all of and acting to support the plunger, means for holding said pinions in mesh with. said racks, and drive mechanism for said pinions.

2. In a baling press, a baling chamber, a plunger the-rein having a plunger head and arms carrying the head, said arms having continuor. racks, each containing two lengthwise extending portions and each arm having a continuous groove running paraL lel with the rack thereof, pinions, one meshing with each rack, shafts for said pinions, there being portions projecting from said pinions andextending into'said grooves, and motor driven shafts.

3. In a baling press, a compression chamber, a plunger therein comprising a plunger head and arms carr in the head continuous racks, one on each arm and having two parallel, lengthwise extending portions,

said arms having continuous grooves running parallel with said racks, pinions, one meshing with each rack, shafts for said pinions, each having a stub end entering the adjacent groove in the arms, power driven gearing for said shafts, hand oper-' ated clutch mechanism, and means operated by the plunger for unclutching said clutch mechanism at the ends of the upper strokes of the plunger.
